Phosphorylation of PPARg in epididymal white adipose tissue in ob/ob mice after treatment with MEK inhibitors. Gene expression in ob/ob epididymal white adipose tissue after treatment with vehicle or either of two MEK inhibitors, PD0325901 or GSK1120212 (n = 7, 7 and 8, respectively). Areas under the curve and gene expression were analysed by analysis of variance.

The inhibitor PD173074 (A) or PD184352 (B) was administered to one uterine horn of Hand2d/d mice on day 3 of pregnancy (n = 5). The other horn served as vehicle-treated control. Uterine horns were collected on the morning of day 4, and sections were subjected to IHC to detect p-FRS2, p-ERK1/2, and Ki-67. (C) IHC of pERa and Muc-1 in uterine sections of Hand2d/d mice treated with PD173074 or PD184352.

(G) Nocodazole-arrested HeLa cells were treated with VX-680 and MG132 and stained for CENP-E (Green), pT422 (Red) and DNA (Blue). (H) pT422 fluorescence intensity was normalized to the total CENP-E fluorescence. Plots show the mean of > 15 cells per condition from two independent experiments.

Effects on PI3K signaling. Tumor cells were treated with DMSO, BEZ-235 (5uM, 1uM), BKM-120 (5uM, 1uM), RAD-001(5uM, 1uM) or cyclopamine (2.5uM, 1uM) for 3 hr. Cells were lysed and protein was analyzed for phosphorylation of AKT and S6 (pAKT and pS6) or for GAPDH by Western blotting.
